Rupert Swarbrick a9b61080a4 Add newlines to help text for dfflegalize 
I think these were probably missed by accident. Spotted because GCC
spits out lots of messages like this:

passes/techmap/dfflegalize.cc:114:7: warning: zero-length gnu_printf format string [-Wformat-zero-length]
  114 |   log("");
      |       ^~

(because we tell GCC that the first argument to log() looks like a
printf control string in log.h, and a zero length such string triggers
a warning).

qbfsat: Fix name-based hole specialization. 
Look for unique connections in the containing module with the $anyconst port Y SigBit on the RHS and use those. If no such connection is found, fall back to using the name of the $anyconst port Y SigBit.

Marcelina Kościelnicka b0bee396a8 Add new builtin FF types 
The new types include:

- FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`)
- FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`)
- FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`)
- FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`)
- FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`)
- latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`)

The new FF types are not actually used anywhere yet (this is left
for future commits).

qbfsat: Fixes three bugs. 
1. Infinite loop in the optimization procedure when the first solution found while maximizing is at zero.
2. A signed-ness issue when maximizing.
3. Erroneously entering bisection mode with no wire to optimize.

a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.
